Iwamodoki is a worm-like Badnik that hides under rocks in the Lava Reef Zone in Sonic & Knuckles. When an enemy approaches, the robot emerges from hiding and will explode after a few seconds, scattering stone debris around it. Even though it self-destructs, its organic battery will still be freed and will flutter away.
